This paper challenges the existing diffuse-strain model of the Africa-Eurasia collision in the western Mediterranean by analyzing two active offshore fault systems: the Yusuf Fault System (YFS) and the Alboran Ridge Fault System (ARFS). Using seismic images, the authors estimate significant Plio-Holocene slip (16 ± 4.7 km for ARFS and a minimum of 12 km for YFS), suggesting a well-defined narrow plate boundary capable of generating significant seismic and tsunami hazards.
